Gram′s safranin solution for Gram staining, for microscopy, Sigma-Aldrich®

Supplier: SIGMA-ALDRICH MICROSCOPY
Description: Gram’s safranin solution, also known as Safranin T or Basic Red 2, is a ready-to-use staining solution that comprises 10% safranin in ethanol. Safranin is a basic, cationic, azine dye containing a planar, diaminophenazine chromophore, with a phenyl substituent attached to a ring nitrogen. The trimethyl cationic form of safranine is lipophilic, whereas the dimethyl forms are weakly hydrophilic. It is most notably used in bacteriology as a counterstain in Gram staining to differentiate between Gram-positive and Gram-negative bacteria.

Gram-Hücker R Kit To differentiate Gram-positive from Gram-negative Bacteria

Catalog Number: (720-0350)
Supplier: RAL (REACTIFS RAL SA)
Description: Gram-Hücker staining is based on the same principle than the Gram-Nicolle staining. The structure of the bacterial walls and their permeability to alcohol help differentiate the Gram-negative bacteria from the Gram-positive ones. In this technique, Carbolic Gentian Violet is replaced by Crystal Violet Oxalate (that does not require filtration) and Ziehl-Carbolic Fuchsin by Safranin.
